CVE-2023-34409: Path Traversal
In Percona Monitoring and Management (PMM) server 2.x before 2.37.1, the authenticate function in authserver.go does not properly formalize and sanitize URL paths to reject path traversal attempts. This allows an unauthenticated remote user, when a crafted POST request is made against unauthenticated API routes, to access otherwise protected API routes leading to escalation of privileges and information disclosure.
